Prostatic cancer is a common cause of morbidity and mortality in the United States. Although many new serologic and radiologic procedures are now used in its diagnosis, the rectal examination still remains the best diagnostic test. Staging is essential for effective treatment. Treatment of prostatic cancer varies, with observation in stage Al; surgery and/or irradiation for stages A2, B, and C; and hormonal or cytotoxic drugs for symptomatic stage D.
